The teacher will present the learning objectives of the lesson. The teacher will present the learning objectives of the lesson. The teacher will present a series of images or real-life examples of objects used in different contexts (medical, sports, electronics, construction, and household items). Each image will depict a familiar item such as: A titanium hip implant A carbon fiber bicycle A smartphone circuit board A concrete wall or steel beam A non-stick frying pan or plastic container The teacher will ask: What foods did you eat today? Which ones do you think are healthy or give you energy? The teacher will show 4 images: sugar cube, butter, raw egg, DNA strand. The teacher will ask: “Which part of your body might each one affect? Why do you think their structure matters?” The teacher will show an animated video demonstrating how reaction rates occur and how various factors such as concentration, temperature, and particle size affect them. Activity: String Engineering The teacher will present a dilemma to learners of making a piece of string strong enough to lift a 3 kg weight. Only its current state, the string can only lift a portion of the weight before it breaks. The learners need to figure out how to make it stronger. The learners can do various things with the string. The only limitation is that they must make the string strong enough to lift a 3 kg weight and that it must be at least 1/2 meter in length Created by: GREG M, Et al Students will reflect individually, discuss with a partner, then share with the class. This introduces carbohydrates, lipids, and proteins naturally. The teacher will let the students make their own models of macromolecules using the provided materials. C.

Created by: GREG M, Et al Activity Title: Biomolecule Detectives Instructions: 1. Group yourselves into 4 teams. Each group will be assigned one biomolecule (Carbohydrate, Protein, Lipid, or Nucleic Acid). 2. Conduct short research using textbooks, own research, or prior knowledge. Use the table below to organize your findings. 3. Present your findings to the class through a 2 to 3 minutes poster talk or minipresentation. The students will answer the following based on their understanding and group sharing: 1. Which biomolecule is the main source of quick energy for the body? 2. Which biomolecule is responsible for genetic information storage? 3. What is the role of proteins in building the body? 4. Why are lipids important despite being high in calories? Discussion with visuals: Carbohydrates: Ring-like structure → soluble in water → quick energy Lipids: Long hydrocarbon chains → nonpolar → energy storage, insulation Proteins: Chains of amino acids that fold → shape-specific → enzymes, hormones Nucleic Acids: Chains of nucleotides with nitrogen bases → sequence stores genetic info The teacher will show flash cards (set of 4 macromolecule structure cards) then the students will match the cards on another separate cards (descriptions of functions and properties) “Stores genetic instructions” “Provides long-term energy and insulation” “Main source of quick energy” “Builds and repairs tissues” Sample Reasoning Guide: Carbohydrate → ring-shaped sugars → quick to break down = fast energy Lipid → long hydrocarbon chains = good for storing energy Protein → folded chain of amino acids = specific shapes for enzymes/hormones Nucleic acid → nitrogen bases in a chain = code for traits The teacher will introduce Collision Theory: Key Factors Affecting Collision Frequency and Energy: a. Concentration – More particles per volume = more collisions. b. Temperature – Higher temperature = faster particles = more energetic collisions. c. Particle size (surface area) – Smaller particles = more exposed surface = more collisions. The teacher will use illustrations to explain how different factors affect the rate of chemical reactions based on Collision Theory. Activity: "Reaction Rate Challenge" Students will work in pairs or small groups. Each group will receive a set of reaction scenarios (printed cards or on slides) that describe chemical reactions with varying conditions. For each scenario, students must: Identify the factor being changed (concentration, temperature, or particle size). Predict whether the reaction will speed up or slow down. 5. What would happen if your diet lacked nucleic acids? Explain their reasoning using Collision Theory. Scenarios: Two beakers contain the same amount of hydrochloric acid. In Beaker A, a small piece of zinc metal is added. In Beaker B, powdered zinc is used. ✅ Factor: Particle Size ✅ Prediction: Beaker B reacts faster ✅ Explanation: Powdered zinc has greater surface area, leading to more frequent collisions. Beaker A contains 1.0 M hydrochloric acid. Beaker B contains 3.0 M hydrochloric acid. Both have the same amount of magnesium ribbon. ✅ Factor: Concentration ✅ Prediction: Beaker B reacts faster ✅ Explanation: Higher concentration means more particles per volume, increasing collision frequency. A tablet is dropped into cold water in Setup A and into hot water in Setup B. ✅ Factor: Temperature ✅ Prediction: Setup B reacts faster ✅ Explanation: Higher temperature increases particle speed and energy, causing more frequent and energetic collisions. Two experiments use the same volume of sodium thiosulfate solution, but one is placed on an ice bath and the other on a hot plate. ✅ Factor: Temperature ✅ Prediction: Hot plate setup reacts faster ✅ Explanation: Heating increases kinetic energy of particles, leading to more successful collisions. A student adds 5 mL of acid to a base in one trial, and 20 mL in another. The volume of base stays the same. ✅ Factor: Concentration (effective particle amount) ✅ Prediction: The 20 mL setup reacts faster ✅ Explanation: More acid particles are available to collide with base particles. Setup A uses granulated sugar in water; Setup B uses powdered sugar in the same amount of Created by: GREG M, Et al water. ✅ Factor: Particle Size ✅ Prediction: Setup B dissolves/reacts faster ✅ Explanation: Powdered sugar has more surface area, increasing the rate of particle interaction. A reaction between baking soda and vinegar is performed at 10°C and at 50°C. ✅ Factor: Temperature ✅ Prediction: 50°C setup reacts faster ✅ Explanation: Higher temperature = higher kinetic energy = more collisions with enough energy to react. Equal masses of calcium carbonate are used, but in one test it's marble chips, and in another, it’s ground into powder. ✅ Factor: Particle Size ✅ Prediction: Powder reacts faster ✅ Explanation: Smaller particles = larger surface area = more collision opportunities. Hydrogen peroxide is added to different concentrations of potassium iodide catalyst. ✅ Factor: Effective Concentration/Catalysis ✅ Prediction: Higher concentration of KI speeds up the reaction ✅ Explanation: More catalyst speeds up the decomposition by lowering activation energy, increasing successful collisions.

Finding practical applicatio n of concepts and skills in daily living B. REMARKS C. REFLECTI ON Created by: GREG M, Et al “The right material in the right place makes all the difference—just like the right choices in life.” Just as materials are chosen for their unique strengths—whether it’s titanium for implants or carbon fiber for sports gear—we, too, have our own strengths and purposes. Understanding our strengths, using them wisely, and respecting the differences in others can help us build a stronger, more purposeful life. C. Provide insulation and long-term energy storage D. Break down glucose for immediate use 5. Which of the following is the correct match of biomolecule and its basic building block? A. Lipids – Nucleotides B. Nucleic acids – Amino acids C. Proteins – Fatty acids D. Carbohydrates – Monosaccharides “Just like biomolecules work together to keep our body healthy, every person has a unique role to play in society.” Each biomolecule has a specific function: carbohydrates give energy, proteins build and repair, lipids store energy and protect organs, and nucleic acids carry genetic information. Despite their differences, they work together in harmony to keep the body alive and functioning. In the same way, each person has unique abilities and responsibilities. We may differ in strengths—some are leaders, others are caregivers, artists, or builders—but when we work together with respect and purpose, we create a healthy, balanced community. “What’s inside determines what something can do—just like how our character shapes our actions.” In science, the structure of biomolecules determines their properties and functions—for example, the folded shape of proteins allows them to carry out specific tasks, while the double-helix structure of DNA enables it to store genetic information. In life, our inner values and character— like honesty, kindness, and perseverance—determine the kind of person we become and the impact we make on others. Just as the right molecular structure is essential for proper function, a strong moral foundation is essential for meaningful and purposeful living. “Success in life, like reactions in chemistry, depends on the right conditions and meaningful interactions.” Collision Theory teaches us those effective collisions—those with enough energy and proper orientation—are needed for a reaction to occur. Similarly, in life, progress happens when we approach opportunities with the right attitude, preparation, and effort. Just as temperature, concentration, and particle size influence reaction rates, our environment, focus, and mindset affect how quickly and effectively we grow and succeed. It’s not just about doing more, but about doing things with purpose and readiness. A. No. of learners who earned 80% on the formative assessme nt B. No. of learners who requires remediation C.
